I know, I'm messing with you.
I was mentioning that WDDM 2.0 is not friendly with older versions of DirectX (which is driver related). The new driver architecture makes it harder to write fast drivers for old DirectX, plus the hardware isn't optimized for such old games anymore. That's basically what I was trying to say. This is why I like having a retro gaming PC and a Win7 install so I can avoid these issues as much as possible.
See? I told you that this thread would be worth it.
One final solution (for Morrowind). Maybe you could try WINE. That should redirect Direct3D8 calls to OpenGL, and NV's OpenGL drivers are much better.
Shogun.
